SAFETY RAZOR BLAE HOLDER Filed April 7, 1944 -atented Sept. 12, 1944vUNITED STATES PATENT OFFICE SAFETY RAZOR BLADE HOLDER Jan de Swart, LosAngeles, Calif., assigner to Plastic Research :Engineering Division VofVictory Manufacturing Co., South Pasadena, Calif., a corporation ofCalifornia Claims.

This invention relates to a safety razor blade holder, and is intended,particularly, to provide a holder which is capable of being readilyformed out of plastic material.

One of the objects of the present invention is to provide a novel formof release mechanism for a safety razor blade.

Another object of the present invention is to provide a novel, curvedrazor blade holder.

Another object of the present invention is to provide a form of razorwhich provides a curved fluted surface adapted to cooperate with acurved cutting blade and so shaped and arranged that an exterior guardfor the cutting blade is not required, and to associate with the holdera novel means for holding the razor blade in position so as to dispensewith the necessity of employing a guard for the blade.

Various further objects and advantages of the invention will beunderstood from the following description of the preferred form orexample of the razor bladevholder embodying the present invention. Forthat purpose I have hereafter described a preferred example of myinvention in connection with the accompanying drawing, in which Figure 1is a side elevation with the razor blade removed.

Figure 2 is an end elevation with the razor blade in position.

Figure 3 is an enlarged, fragmentary side elevation, mainly in verticalsection.

Figure 4 is a top View of a razor blade for use in connection with theholder of the present invention.

Referring to the drawing, the razor blade holder comprises a body formedof plastic Inaterial which is provided with a handle 2 and atransversely extending blade-holding head 3. The blade-holding head 3 isprovided with a curved and fluted face 4 for cooperating with the safetyrazor blade 5. The safety razor blade 5 is preferably curvedlongitudinally to closely conform to the curvature of the holes wherethe blade contacts the holder. The fluted surface of the holder permitsthe razor blade to fit closely against the holder, the flutes providingan opening for the hairs cut by the blades. By this form of the holdeiand blade it is possible with the razor of the present invention todispense with the necessity of employing any guard for the blade.

The holder is provided with a fixed hookshaped member 1 and a movablehook-shaped member 8, the two facing outwardly in opposite directions.The hook-shaped members 'I and 8, in practice, pass through therectangular opening 6 of the blade and secure the blade to the holder.The member 1 is integral with the head 3 of the body, while the hook 8is attached to a plunger I0 which is reciprocably mounted in alongitudinal bore I I in the head 3. The plunger Ill is yieldably urgedinto blade-holding position by a coil spring I2, positioned in the boreII. A slightly elongated opening 9 is provided in the head 3 in orderthat the shank of the hook 8 may connect with the plunger I0 and alimited movement be provided for the plunger II).

The holder is provided With an opening I3 in one of its ends and anoperating button I4 connected to the plunger which extends through theopening. By means of the button I4 the two hooks 'I and 8 may be pressedtogether sufficient to release the blade 5.

For construction purposes, the end of the holder portion I3 may beprovided with a cap I5 having a sliding t with a reduced cylindrical4flange I6 integral with the body of the device. After the spring andplunger have been assembled in the device, the cap I5 may besubstantially integrally united with the remainder of the holder by theuse of acetone, or similar solvent for plastic, for joining the cap I5to the body.

While the particular form of the invention herein described is welladapted to carry out the objects of the invention, various modificationsand changes may be made, and this invention is of the scope of theappended claims.

I claim:

1. A razor blade holder formed principally of plastic material, saidholder comprising a body member having a blade-holding head and a handleextending transversely to the handle, said head having a stationaryblade-holding hook and a movable blade-holding hook attached to aplunger movable in said bore, and spring means for yieldably urging saidplunger outwardly.

2. A safety razor blade holder formed principally of plastic materialand including a plastic body having a blade-holding head and a handleextending from the head, the head having a fluted and curved surface, ablade-holding hook protruding from the curved surface of said head, amovable blade-holding hook protruding from the surface of said head andattached to a plunger, a transverse bore in said head in which saidplunger is movably mounted, and spring means yieldably urging saidplunger into the expanded position.

3. A safety razor blade holder formed prinmeans yieldably urging saidplunger into the expanded position; the head having a separatelyformedcap for'holding the plunger within the bore.

4. A safety razor blade holder comprising a 'body having a blade-holdinghead and a handle portion integrally formed of plastic material, the

head having a separately formed cap member permanently united to saidhead, a transverse bore through the head, a spring-actuated plungermovable in said bore and carrying a blade-holding hook, said head havinga curved and fluted surface for contacting the razor blade.

5. A safety razor comprising a curved razor blade and a holder, saidholder including abody member formed of plastic material and having ablade-holding head and a handle extending therefrom, the head beingprovided with a stationary blade-holding hook, a movable bladeholdinghook attached to a plunger, and a transverse bore through said head inwhich said plunger is movablyV mounted, and a spring Vnormally urgingsaidplunger into the expanded position.
